United States Patent REMOVABLE COVER LAWN CHAIR Carl Straub, NebraskaCity, Nebr. Application August 28, 1953, Serial No. 377,033

3 Claims. (Cl. 155-54) The present invention relates to chairs of thetype normally used out of doors.

It is an object of this invention to provide a lawn chair, the frameworkof which will not deteriorate when exposed to the weather.

It is another object of this invention to provide an outdoor chair withback and bottom portions which are easily removable for cleaning andstoring since out-of-door chairs readily become soiled and unfit to situpon.

It is a further object to provide a lawn chair fulfilling theabove-stated objectives, yet retaining a measure of the comfort of moreexpensive chairs due to the inherent resiliency of this construction.

Yet a further object is to provide a chair as described which has armswhile retaining its simplicity and economy of construction.

Yet another object of the invention is to provide a device for thepurpose described which is sturdy and durable in construction, reliableand efiicient in operation, and relatively simple and inexpensive tomanufacture, assemble and utilize.

Other and further objects and advantages of the present invention willbe apparent from the following detailed description and claims and areillustrated in the accompanying drawings which, by way of illustration,show the principles of the invention and a mode in which I havecontemplated applying those principles.

Other embodiments of the invention embodying the same or equivalentprinciples may be used and structural changes may be made as desired bythose skilled in the art without departing from the present inventionand the purview of the appended claims.

In the drawings:

Figure 1 is a perspective view of the lawn chair of this invention. Theback and bottom portions together with the framework therefor are shownby dotted lines in the downward position they assume when the back andbottom cover portion is being removed for cleaning or storing.

Figure 2 is a partial top plan view of a forward corner of the chairsseat at one place where the two sections of the framework are hingedtogether. The seat cover and the adjacent framework is broken away andshown in section.

Figure 3 is a sectional view taken on lines 33 of the seat corner shownin Figure 2.

Figure 4 is a perspective view of a modification of the presentinvention wherein the arm rests are eliminated and the framework issubstantially of one piece construction.

Figure 5 is a perspective view of a refinement of the chair shown inFigure 4.

Referring to the drawings for a more particular descrlption, theframework of the lawn chair is preferably made of stainless steel oraluminum tubing, although other material of other formations would alsobe suitable.

As shown in Figure 1, the chairs framework is in two Sections; thepedestal, armrest, and back support frame 'ice portion 12 and the seatand back frame portion 14.

The frame portion 12 is preferably formed of one continuous piece ofmetal tubing, wherein all corners are well-rounded to retain thestrength of the tubing.

Located at the forward side of the chair, two spaced apart, parallelupright leg sections 16 are formed integrally at their lower ends withforward ends of the sides of a C-shaped pedestal base section 18, whichlatter is horizontal and rests upon the ground.

The middle portion of the C-shaped base section 18 is transverselydisposed with respect to the chair proper and is located at the rear ofthe chair.

Spaced vertically above the base 18 another C-shaped frame section 20 islocated having a horizontal, transversely disposed back support part 22and two horizontal arm rest parts 24, which latter each extend forwardlyand at their forward ends curve downwardly into the described uprightlegs 16.

A transversely disposed brace 26, welded or otherwise secured at eachend to the middle of the legs 16, extends horizontally therebetween.

The seat and back frame portion 14 is of one-piece construction and, asbest shown in Figure 3, the two ends 28 of the horizontal side parts 29have been flattened from their original tubular shape and are downwardlybent into a circle around each end of the described horizontal brace 26to form hinges which latter are located closely spaced inwardly from theupright legs 16 and allow the frame 14 to pivot forwardly in a verticalplane.

From the two widely spaced apart ends 28, the sides 29 of the frameportion 14 extend horizontally rearward and there curve up to joinback-side parts 31 which are connected by a transverse horizontal backportion 32. The two parallel side parts 31 of the frame- 14 rest againstthe inside of the back support member 22 of the frame 12.

A slip cover 35 for the chair is preferably made of canvas or similarmaterial in a sack formation. The sack formation includes a flat upperside 36 normally closely spaced apart from a flat lower side 38, thespacing being approximately the thickness of the frame section 14.

The slip cover 35 has a flap 42 which protrudes outwardly from the upperside 36 of the cover 35 and is in use folded down, across, and under thebrace 26.

Inwardly from the folded end of the flap 42, and transversely disposedthereacross is a row of spaced apart, female snap rivet buttons 46secured through the canvas. A transverse row of similarly spaced apartmale snap rivet buttons 48 are secured in the forward edge of the lowerside of the cover 35.

When installed for use the sack-like cover 35 is pulled over the seatand back frame 14 when the latter is pivoted forwardly as shown inFigure 1, and the flap 42 is then wrapped around the horizontal brace26.

The snap buttons 46 and 48 are aligned with each otherand snappedtogether to removably secure the cover 35 to the frame 14.

The chair modification shown in Figure 4 is also provided with twospaced apart upright parallel legs 52 curving backward at their lowerends into a C-shaped base 54, which latter is identical with the base 18of Figure 1.

The upper ends of the legs 52 curve to a horizontal direction. Thesehorizontal portions 54 extend backwardly and then extend upright as at56 where they are integrally met by a transverse horizontal section 58.The foregoing described frame is of one piece construction.

A horizontal transverse tube 60 is welded or otherwise suitably securedbetween the upper ends of the legs 52, whereby a sack-like slip cover64, provided with a flap 66 at the open end thereof and matching rows ofsnap rivet buttons 68 thereon, is pulled over the top of the PatentedNov. 20, 1956 chair 50 and is snapped around the said horizontal tube6.0.

In the use of this chair for outdoor purposes and as shown in Figure 1,the slip cover 40 may be easily removed by pivoting the seat and backframe 14 to a partially inverted forward position and the snap buttons46 and 48 are then released, whereby the cover 40 may be slipped oif forwashing or storage.

The slip cover 64 of the modified chair 50 may also be easily removed ina similar manner.

The construction of both chairs is such that when a person rests hisfull weight upon the covers the tubular frame portions will springlightly toward each other for allowing the give that is necessary forcomfort.

In Figure the C-shaped base membenkthe upright leg members 52 and thehorizontal portion 54 are the same as shown in Figure .4. The uprightportions 70 corresponding with the portions 56 of Figure 4 curvebackwardly and extend into the horizontal back support 58 throughcarefully rounded corner portions 72.

Horizontal transverse tube member shown at 60 in Figure 4 is modified asfollows: a tube member 74 is of slightly curved formation and connectswith the uprights 52 at a position below the point where the uprights 52bend and continue into the horizontal portions 54.

The curvature of the tube 74 allows for additional comfort since astraight rigid bar does not contact the limbs of a sitter. The curvatureof the portion 70 and the round corner 72 provide the same comfort atthe top of the back of the chair since the sitter does not lean directlyagainst a horizontal unyielding bar.

The cover 35 is of the same formation shown in the previously describedfigures and its method of removal is the same as for the modificationshown in Figure 4.

The same flap 42 curves around the rod 74 and fastens by means of thesame snap button formation 46 and 48 shown in detail in Figure 3.

As described, the construction of the chairs will not be subject todeterioration from weather or hard usage whereby their period of usefulservice will be appreciably lengthened.

From the foregoing description, it is thought to be obvious that a lawnchair constructed in accordance with my invention is particularly welladapted for use, by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification Withoutdeparting from the principles and spirit thereof, and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice, except as claimed.
